Kusiyana pakati pa HDPE ndi PE

HDPE imadziwikanso kuti polyethylene yapamwamba kwambiri.Ndi mtundu wa utomoni wa thermoplastic wokhala ndi crystallinity wapamwamba komanso wopanda polarity.Maonekedwe a HDPE yoyambirira ndi yoyera yamkaka komanso yowoneka bwino pamlingo wocheperako.Polima si hygroscopic ndipo imakhala ndi mpweya wabwino wamadzi, womwe ungagwiritsidwe ntchito pakuyika.HDPE ili ndi mphamvu zamagetsi zamagetsi, makamaka mphamvu yamagetsi yamagetsi yamagetsi, yomwe imapangitsa kuti ikhale yoyenera kwambiri pamawaya ndi zingwe.Magulu apakati mpaka apamwamba amakhala ndi kukana kwambiri kutentha kwapakati kapena -40f kutentha kochepa.HDPE nthawi zambiri imagwiritsidwa ntchito ngatikuyika chitoliro, komanso enazoseweretsa, pulagi ya PK , audio.

Chifukwa cha mphamvu zosiyanasiyana, mapaipi a HDPE ayenera kukhala ndi mphamvu zina.Nthawi zambiri, ma resin a PE okhala ndi kulemera kwakukulu kwa maselo ndi zinthu zabwino zamakina, monga ma resin a HDPE, ayenera kusankhidwa.Mphamvu ndi 9 nthawi ya chitoliro wamba polyethylene (PE chitoliro).

Kukana kuvala kumasiyana.Pakati pa mapulasitiki onse aumisiri, HDPE ili ndi kukana kwambiri kuvala.Kulemera kwa mamolekyu, kumapangitsa kuti zinthu zisavale, komanso kuposa zipangizo zambiri zachitsulo (monga carbon steel, zitsulo zosapanga dzimbiri, bronze, etc.), PE wamba ndi gawo limodzi mwa magawo khumi a HDPE.

Mapaipi a HDPE ali ndi zosintha zosiyanasiyana.Ndiwo mankhwala olowa m'malo a mapaipi achitsulo achikhalidwe ndi mapaipi amadzi akumwa a polychloroprene.Komabe, PE polychloroprene ingagwiritsidwe ntchito ngati chitoliro chakunja, ndipo ngakhale mapaipi otsika kwambiri a PE angagwiritsidwe ntchito pamadzi okha.

Kuchuluka kwa ntchito ndi kosiyana.HDPE mapaipiamagwiritsidwa ntchito makamaka: njira yoperekera madzi ya zomangamanga zamatauni, nyumba zopangira madzi m'nyumba, njira zoperekera madzi m'manda ndi kukwiriridwa madzi m'malo okhalamo komanso malo obzala, kukonza mapaipi akale, makina opangira madzi opangira madzi, mapaipi amadzi am'mafakitale minda, ulimi wothirira ndi minda ina.Mapaipi apakati apakati a PE ndi oyenera kunyamula gasi, gasi wachilengedwe ndi gasi wamafuta amafuta.Mapaipi otsika kwambiri a PE ndi ma hoses.
